摘　　要：对华北平原不同保护性耕作方式下冬小麦生长及产量效益的影响进行了研究。试验设置了秸秆不还田翻耕、秸秆还田翻耕、秸秆还田旋耕、秸秆还田免耕4个处理。结果表明:从冬小麦的地上部和地下部生长情况和产量、产值来看,多数性状表现为秸秆还田翻耕>秸秆还田旋耕>秸秆还田免耕;从劳动生产率来看,秸秆还田免耕的劳动生产率最高为24.48%,其次为秸秆还田翻耕,再次为秸秆还田旋耕,对照的劳动生产率为最低;从产投比来看,秸秆还田旋耕处理的经济效益较好,适宜推广。The growth and yield of the winter wheat under different protective tillage in the North of China plain were studied. Four treatments were set： no straw returning and deep-tillage （NSDT）, straw returning and deep-tillage （SDT）, straw returning and rotary-tillage （SRT） and straw returning and notillage （SNT）. The results showed that from the growth and productivity of winter wheat, SDT 〉 SRT 〉 SNT in the most of the traits. The labor productivi- ty of SNT was 24.d8%, which was the highest. The labor productivity of SDT, SRT and NSDT was 21.06%, 18.86% and 15.45% respectively. According to the ratio of outputs to inputs, the economic benefits of SRT were the highest, which was suitable for promotion.
